The topic I want to discuss is seed saving
and storage of strictly cannabis seeds.
As of 2019 best information available tells us:
Hemp is possibly one of the earliest plants to be cultivated.
Cannabis has been cultivated in Japan since the pre-Neolithic period,
for its fibres and as a food source, and possibly as a psychoactive material.
An archeological site in the Oki Islands near Japan contained cannabis achenes
from about 8000 BC, probably signifying use of the plant.
Hopefully with this information we will be able to save seeds for many more years to come!
EDITED TO ADD INDEX TO THREAD FOR QUICK SEARCH OF INFO
After spending years on this subject its been my observation that to each their own
By that I mean you may have different storage needs based on what your goals are…
For short term plastic is fine 1-2 years
microscopic structure of plastic more of a weave
(the reason this is not a long term storage option is because plastic is permeable )
If you ever smell dank in plastic even triple wrapped it dont stop odor
Same bud in non permeable glass and metal lids top notch for a few years
Go with ampoules sterile cotton and bentonite clay in the fridge for the win

Ideal moisture content (MC) is 8% for hemp seed storage
Agricultural Science Procedia 5 ( 2015 ) 170 – 176
The hemp seed moisture content is typically between 15-20 % at the time of harvest and the final moisture content for storage and pressing should be below 10%. Ideally 8%
Seeds are heated at prescribed temperatures for prescribed times, and all weight loss is considered to be moisture. Weighing samples before and after drying provides the data for calculation of moisture content.
Montmorillonite Clay is a naturally occurring porous adsorbent. The mined clay is activated for use as a desiccant through careful drying. This clay will successfully regenerate for repeated use at very low temperatures without substantial deterioration or swelling. However, this property causes clay to give up moisture readily back into the container as temperatures rise. Clay is inexpensive and effective within normal temperature and relative humidity ranges (Table 1). Some variation in performance can be seen due to its source as a naturally occurring material.
Silica gel is a partially dehydrated form of polymeric colloidal silicic acid. Silica gel has an amorphous micro-porous structure with a distribution of pore opening sizes of roughly 3-60 angstroms. These interconnected pores form a vast surface area that will attract and hold water by adsorption and capillary condensation, allowing silica gel to adsorb up to 40% of its weight in water. Silica gel is extremely efficient at temperatures below 77°F (25°C) (see Figures 1 and 2), but will lose some of its adsorbing capacity as temperatures begin to rise, much like clay (Figure 3). Much of silica gel's popularity is due to its non-corrosive, nontoxic nature and its having received US government approval for use in food and drug packaging.
Cannabis seeds at 8% Moisture Content do not mush when squeezed they shatter

Loss on drying
The classic laboratory method of measuring high-level moisture in solid or semi-solid materials is loss on drying.[4] In this technique, a sample of material is weighed, heated in an oven for an appropriate period, cooled in the dry atmosphere of a desiccator, and then reweighed. If the volatile content of the solid is primarily water, the loss on drying technique gives a good measure of moisture content.[5] Because the manual laboratory method is relatively slow, automated moisture analysers have been developed that can reduce the time necessary for a test from a couple of hours to just a few minutes. These analysers incorporate an electronic balance with a sample tray and surrounding heating element. Under microprocessor control, the sample can be heated rapidly. The moisture loss rate is measured throughout the process and then plotted in the form of a drying curve.[6]The hemp seed moisture content is typically between 15-20 % at the time of harvest and the final moisture content for storage and pressing should be below 10%. Ideally 8%
